Change testing scripts (example_scripts/ACESgrid) accordingly. + +checkpoint61r +o pkg/seaice: + - clean up the 3-time levels of UICE,VICE,HEFF,AREA in three steps: + 1. introduce fields for time step (N-1) + 2. do not use levels 2 and 3 anymore (but keep them) + 3. replace 3D versions of UICE,VICE,HEFF,AREA by 2D versions.

+ +checkpoint61q +o pkg/seaice: fix bug in free slip boundary conditons for LSOR solver + - the boundary conditions along open boundaries are unclear, because the + associated masks are set to zero and are thus treated as closed when + applying the slip-boundary conditions. + - move initialisation of grid variables from seaice_init_varia to _fixed +o adding doc/diags_changes.txt +o model/src: + do_the_model_io: rename few pkg S/R which are called from do_the_model_io, + to avoid "_diags" naming if no relation to pkg/diagnostics. + ini_theta,ini_salt: fix (at least compile the code) reading from NetCDF + file and only call PLOT_FIELD_XYZ if debugMode=T. + remove few PLOT_FIELD_XY calls outside initialisation. + remove few unnecessary BARRIER. +o pkg/salt_plume: add SaltPlumeSouthernOcean to allow disabling + of salt_plume package in Southern Ocean +o pkg/thsice: + - fix hOceMxL in overlap (needed for sea-ice advection); + update output of experiment global_ocean.cs32x15.icedyn. +o pkg/seaice: + - make the (placeholder-)tracer IceAge a little more meaningful + by avoiding ridging of age due to convergent ice flow + - add diagnostics for surface temperature, atmospheric and oceanic + heat flux, and atmospheric and oceanic ice growth + +checkpoint61p +o eesupp (global_max & global_sum): + - add one more element to buffer (start at index 0) for GL_MAX/SUM output; + - remove starting & endding barrier (no longer needed) +o pkg/mdsio, writelocal: + works also in multi-threaded when LOCBIN_IO_THREAD_SAFE is undefined + (remove the STOP): uses shared buffer IO to store data from all threads + and then let master-thread write nThreads tiles. +o pkg/mdsio (read/write field): + - tiled IO done in 1 piece (all levels at a time); + - new header file "MDSIO_BUFF_3D.h" with 3-D buffers. + - multi-threaded: allow to read/write local (non-shared) array + (was already working with singleCpuIO ; now works also without); + => no longer needs barrier call after reading a file (added inside + mds_read/write field). + - move barrier calls outside gather/scatter_2d to mds_read/write_field +o pkg/obcs/exf + - exf_getffieldrec.F: add a few ". _d 0" and + add code to catch the case fldperiod = 0. + - obcs_precribe_read.F: change if statements so that they match + the variable type (_RL) + - add a separate exf_iprec_obcs to exf_set_obcs (by default equal to + exf_iprec) as part of namelist EXF_NML_01 +o pkg/mdsio: + - read/write tiled (local) files: read/write 1-level tile chunk at a time + (instead of segment of length sNx); expected to speed up tiled IO. +o pkg/exch2: + - take buffer copy from/to array out of S/R exch2_send/recv into new + S/R exch2_put/get ; Exch of local variable now works with MPI+MTH + (tested by removing commom block statement in SOLVE_FOR_PRESSURE.h). + - ad version of send/recv no longer needed (but needs exch2_ad_put/ad_get) + - simplify argument list of S/R exch2_get_uv_bounds and exch2_get_scal_bounds + (which replaces exch2_get_recv_bounds & exch2_get_send_bounds) by + including Topology header file (and common blocks). + - implement EXCH_IGNORE_CORNERS in scalar exchange (rx1); + remove 2nd exch call in exch2_s3d_rx (no longer needed). + - document S/R arg. list (+ update some comments) +o pkg/seaice: + - added SEAICE_CLIM_AIR code, which permits modulation of surface air + temperature and humidity over sea ice based on climatological values. + - clean up computation of Hibler+Bryan (1987) stress coupling for the case + of LSR (this change is expected to change the results slightly because now + it uses slightly difference moduli from the second last LSR solution, but + that is more consistent with the stress computations; this part of the code + is not tested in the verification experiments) + - fix diagnostics for flux of ice in case of B-grid + - turn strain rates eij and press into global fields within global + common block in SEAICE.h for more straighforward diagnostics + - fix diagnostics for principal stress components, press, zeta, eta + to give something meaning full +o change tiling of global_ocean.cs32x15 (12 tiles, 32x16) and generate + new output (all 4 tests) using default rotationPeriod. +o pkg KPP: + - add flag (LimitHblStable) to avoid limiting BL depth under stable conditions + - fix vertical indices in RI_IWMIX (match between KPP grid from 0 to Nr+1 + and normal grid from 1 to Nr) +o Fix computations of L4rdt in mom_calc_visc.F +o eesupp: + new S/R ALL_PROC_DIE (like EEDIE, without irrelevant threads err msg): + should be called before a "stop" if we know that all process are going + to stop; if one Proc does call this S/R, will hang in MPI_FINALISE. + checkpoint61o o pkg/exch2: change check_depths to issue just a warning (instead of error+stop) o model/src/ini_curvilinear_grid.F:
